Eh. Calories are… Tricky. What is a calorie? A unit of food which, when burned, will heat a gram of water by 1 degree Celsius. But your body isnt just a furnace, it’s complex. And everyone’s is physiologically different - we aren’t all running at the same efficiency (base metabolism). And not all calories are available. For example, fiber is not digestable and can’t be absorbed by the digestuv system and it also associates with sugars which also prevents them from being absorbed. So, eating whole fruits will result in absorbing less sugar than drinking juice which has the same total amount of sugar.
For sure it can conceptually be boiled down to calories effectively absorbed and calories burned. But digging into what that actually means can actually be quite tricky.

Your body is so much more complicated than a function that takes calories as input and outputs an expected result. You need more than just calories, you need nutrients. A nutrient deficient person does not burn calories the same way a person with a balanced diet does.
Like just think for a second. Is the only variable of food that matters is calories, then why do you need vitamins? Why do we split calories into categories like protein, carbs, veggies, fruits, etc? Why can you get a PhD in nutrition if it’s only as simple as calories in calories out?
The simple answer is it’s not simple. Asserting that it is when it isn’t creates some terrible narratives around exercise, diet, and body image.
